Your driver’s license could soon live on your phone. Here’s what you should know.

As these digital IDs become more readily available, some are concerned that they could be used for tracking. In a report published in May, the American Civil Liberties Union warned that state motor vehicle departments could feasibly collect information about “every bar, club, casino, office lobby, bank, pharmacy, doctor’s office, and airport that you visit.” That starts to sound even worse if your state’s DMV has an agreement in place to share that information with local police — a practice the ACLU says is common.
